*nodecreatelinemarkparams

Creates nodes or points at parametric locations on lines.

*nodecreatelinemarkparams entity_type mark_id double_array number_of_doubles insert_count mode point_flag

HyperMesh Tcl Modify Command

Creates nodes or points at parametric locations on lines.

entity_type: The type of input entity. Must be set to lines.
mark_id: The ID of the mark of input entities. Valid values are 1 and 2.
double_array: The ID of the double array that contains the parametric location values in the range 0 to 1. The double array is created using the *createdoublearray command. This should always be set to 1.
number_of_doubles: Integer indicating the size (number of doubles) in the double array created using *createdoublearray.
insert_count: The number of additional parametric values inserted between the values specified by double_array.
mode: Specifies how parameters specified in double_array are used. Valid values are:; 0 - Line arc length parameterization is used; 1 - Internal line parameterization is used
point_flag: Specifies whether nodes or points are created. Valid values are:; 0 - Create nodes (default); 1 - Create points

To create nodes on all lines at arc length parametric values 0.2, 0.8 and 0.8:

*createmark lines 1 all
*createdoublearray 3 0.2 0.8 0.85
*nodecreateatlinemarkparams lines 1 1 3

To create 10 points on all lines using the line’s internal parameterization with parameters equally distributed between 0 and 1:

*createmark lines 1 all
*createdoublearray 2 0 1
*nodecreateatlinemarkparams lines 1 1 2 8 1 1

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:

if { [ catch {command_name...} ] } {
   # Handle error
}
